Light weight tubeless valves are great. Broken light weight tubeless valves are not. For anyone that has ever experienced the sadness of a broken aluminum valve, Traben may have the answer. While the valves are claimed to be just one gram heavier than a comparable aluminum valve, they claim to be four times as strong.
They also have a number of smart features like an “86% larger thru hole” than a typical valve which should allow for more air flow – even after the sealant builds up on the inside. The bottom of the valve is also shaped with their ‘Bead Shed Technology’ which is a beveled edge designed to prevent the tire bead from hanging up when installing tires.
The valves are available in the U.S. through Lindarets, who also offers a Refresh Kit for $7.50 when you buy a set of valves. That Refresh Kit includes two spare sets of valve cores and gaskets as well as a valve core tool to keep your valves sealed and flowing. If you don’t buy the kit with your valves, you can order it after the fact for $9.95.
The weight is claimed to be 5g per valve stem, or 5.3g per valve stem with a plastic dust cap. Available in Natural Ti, Natural with blue, Natural with Red, Gold, or Off-Black, the 44mm length valves are sold in a set of two for $39.95.
